Q:The specific content is what gb/t2608-2012 brick
The provisions of the brick classification, technical requirements, test methods,
Q:Common bond brick?
When adding ingredients, the amount of lime added shall be converted to CaO, and the amount of addition varies depending on the product, usually fluctuating at 1.5~2.5%. For example, the production of coke oven silica brick, the dosage of CaO is 2.0~3.0%; the production of electric furnace top brick, the dosage of CaO is 1.4~1.75%.
Q:Why in the production of the brick to detect the volume density
Product quality control of silica brick.
Q:The brick is mainly used in the place?
Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
Q:The high thermal conductivity of silica brick and traditional brick what is the difference?
The scale quartz is a spear shaped double crystal structure, very compact and favorable to the increase of thermal conductivity. The high thermal conductivity of silica brick in improving thermal conductivity and other performance indicators and traditional coke silicabrick agreement.That is to say, the high thermal conductivity of silica brick all inherited the traditional advantages of coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity
Q:What are the main constituents of refractory bricks?
Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:
Q:What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you
Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.
Q:Glass kiln brick for physical and chemical indicators?
Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.
Q:What role does silica play in refractories?
Low fractory refers to the alumina content between 10%~30%, SiO2 content is less than 85%, semisilica brick SiO2 = 65%,The SiO2 content of not less than 93%, refractory material to natural quartz rock as the main raw materials are called silica, silica brick, silica brick, quartz glass and special products. China's literature generally put this type of product is called "siliceous refractory products", which is the most important brick.
Q:The production of brick, the ingredients of why join the waste brick
The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem
